| Abstract: | A research for structural dynamic optimization design of composite rotor blades is summarized. After basic type of rotor 1mb and blade are determined preliminarily it is the main methods to adjust frequencies by varying blade's mass and stiffness distribution. The designability of composite rotor blade and the changeability of cross section structure offer nimble and effective methods to frequency designs.The finite element methods and numerical optimization are used to optimize the mass and stiffness distribution of blades, in order to adjust frequencies, to improve blade's natural frequency and dynamic properties for struetures, to reduce vibration and to lower the mass. Computer aid design of the rotor blades has partly been achieved. Two living examples of composite rotor blades, “BO-105” and “Douphin” have been calculated. |
